Elizabeth Toy, 29, had told Patch that she would do anything to fight and stay alive for her son Matthew, 11.
Matthew will go to live with his grandmother, a close friend said.
Donations are still being accepted in Elizabeth Toy's Suffolk County National Bank account, friends said, to help give Matthew a secure future.
A pig roast/motorcycle run fundraiser that had been planned will still go on, on October 5 at Four Doors Down in Mattituck, to raise funds for Matthew. The event will begin at 10 a.m., when participants can sign up for a motorcycle run for $20. Next will come the event, which will cost $15 and include a buffet, Chinese auction, a band, The Locals, and a 50/50.
Toy had just signed up as a member of the Cutchogue Fire Department before she got sick.
"She was the most amazing person I've ever met," one friend said. "If you were having the worst day of your life, she'd come over and be silly and put a smile on your face."
Funeral arrangements have not yet been determined.
For months, Elizabeth Toy, consumed with worry over finances and how she will be able to support her young son, turned to the internet for help.
In early September, caring friends posted on North Fork Patch's boards about the challenges Toy, 29, faced.
On her Go Fund Me page, where Toy posted an online plea for donations to help as she faced a life-threatening illness, Toy kept friends and loved ones updated.
In early September, Toy said she continued to recover at the Stony Brook University Cancer Center, where she had a bone marrow stem cell transplant to help treat Hodgkin's lymphoma.
Toy reported that the donor cells were beginning to graft, but with "painful complications," and a forecast of at least two to three weeks before she could return home to her son.
She returned home three weeks ago, only to undergo complications.
On her page, Toy had said she was frantic with worry about having a home to return to — a safe place for herself and her son.
"We are going to need as much help for rent and after care as possible," she said.
With a goal of $15,000 listed, Toy had raised $5400 so far.
Toy said all funds were transferred into a fund set up to pay bills.
Of her ordeal, Toy wrote, "It's really the hardest thing I've done. There are nights where I haven't been sure I'd even see the next day, but I pray and think of home. Please help us to keep that home."
She added, "It's going to be a long recovery, with many setbacks along the way. I want to thank you all again, and remind you to not take people for granted. Appreciate them while they are here. Set aside differences, strive to lift people up, not hold them down. But most of all, love and be loved."
In April, Toy shared her story with Patch. Only 29 years old, Cutchogue resident and single mom Toy described facing the most terrifying specter a parent can imagine: The fear that she might not live to see her son grow up.Toy, who had Hodgkin's lymphoma, a cancer that spreads through the lymph nodes, was first diagnosed in 2010.
Good news came when a donor match for her bone marrow stem cell transplant was found.
But despite the positive, Toy was burdened with worry and buried beneath financial woes. Fighting illness, Toy had to continue to work to pay her rent and provide for her son.
To that end, she turned to Go Fund Me, an online website for raising funds through donations.
"I am struggling against all odds," she wrote on the Go Fund Me website. "I am a single parent who lost my fiance, our only son's father, to deportation in 2009. I was diagnosed with cancer just a year later."
According to her plea, Toy does not receive rental assistance due to the fact "waiting lists are always full or closed."
Toy said along with limited disability benefits of $427 per month, she continued to work at East End Nephrology in Greenport, against doctor's orders.
"I am forced to work sick, oftentimes running to the bathroom to vomit, fighting off shakes and barreling through fatigue against doctor's orders, and putting myself in danger . . . just to make rent, which is $1000 a month, utilities not included," she wrote.
Throughout her struggle, Toy said, she remained focused on staying alive for her son. "My son is so important to me," she said. "I truly am all he has."
Even more frightening than facing cancer, Toy said, was the thought of leaving her son without his mother. "It's the worst nightmare a parent can ever think of," she said. "If I pass away, his father is not in the picture. He would be an orphan."
Her son, she said, is her biggest support and champion. "I told him, 'We don't know what the outcome is going to be, but I'm going to give it my best shot. No matter what I have to go through, I'm doing it for you."
In the past, friends raised funds locally in a trust set up at Suffolk County National Bank in Cutchogue through an account called the "Support Elizabeth Toy Fund" which is still in place, she said.
Funds, however, Toy said, had been depleted. "I cannot come so far and go through all this to lose everything when I come home," she wrote on the Go Fund Me site.
"I will be out of work and in need of help to supplement my rent, utilities and transportation, and child care for six months total, including the transplant itself," she said. "I promised my son Matthew I would never give up, that I would work as hard as I could to push through this and come out on top. Please help me keep my promise to my little boy. He, too, has lost so much, and I don't want him to lose the stability of the home we have built together."
After the transplant, she said, the possibility of graft versus host disease existed, she said, which would even further hospitalization.
Over the past months, Toy endured six different courses of chemotherapy, radiation, a bone procedure where cancer was removed and replaced with cement, and an auto stem cell transplant, which failed.
Even if the transplant didn't work, she prayed for the hope of another trial drug.
"Maybe it will buy me a little more time," she said. "Precious time, that I can have with my son, to teach him all I want to teach him in an entire lifetime. I have to pack it all in."
Toy's primary care doctor, Blaise Napolitano of Hudson River Healthcare, Inc. in Greenport, said she had multiple rounds of chemotherapy and radiation, but her body hadn't responded. The bone marrow transplant, he said, was critical.
"She's very nice," he said. "So very young — a very nice young woman. It's a really sad story. A really sad case."
